Abstract

Penelitian untuk mengetahui pengaruh kerusakan buah semu jambu mete terhadap viabilitas dan pertumbuhan benih jambu mete telah dilakukan mulai bulan Januari  sampai  Desember 2009 di Kebun Percobaan Cikampek, Jawa. Bahan yang digunakan adalah benih jambu mete dari Desa Watukawula, Kecamatan Wewewa, Kabupaten Sumba Barat Daya, Propinsi Nusa Tenggara Timur. Percobaan disusun dengan dua taraf perlakuan yaitu benih jambu mete yang berasal dari buah semu normal beraroma harum dan benih yang berasal dari buah semu rusak mengering. Jumlah sampel yang digunakan untuk mengetahui perkecambahan benih dan bobot serta ukuran benih sebanyak 60 butir benih setiap perlakuan, sedangkan untuk mengetahui pertumbuhan bibit digunakan 30 polybag pada setiap perlakuan. Analisis data dilakukan dengan uji t pada taraf 5% secara  berpasangan. Hasil penelitian menunjukkan bahwa kerusakan buah semu berpengaruh terhadap bobot, tebal, dan viabilitas benih serta pertumbuhan tinggi bibit, sedangkan panjang dan lebar benih, serta diameter batang dan jumlah daun tidak berpengaruh. Bobot dan viabilitas benih jambu mete asal buah semu normal 6.7 g dan 77.7 %, sedang asal buah semu rusak 4.7 g dan  51.0 %.Viability of seeds taken from abnormal cashew applesABSTRACTViability of seeds taken from abnormal cashew apples. The experiment was carried out from January  to December 2009 to know about effect damage of cashew apple to the seed viability and growth of cashew seedling on Cikampek Experimental Station, West Java. Material was used cashew seed from Watukawula village, Wewewa Sub District, Southwest Sumba district, province of Nusa Tenggara Barat. The experiment was arranged with observation on two treatment i.e : Seed was harvested  with normal cashew apple and seed was harvested with damaged cashew apples. Number of sample was used to know the seed viability is 60 seeds for each treatment, further more to know the growth of cashew seedling was used 30 polybag per treatment. Analysis was used t-Student test with 5% level paired. Result of this experiment showed that the good seed viability was seed from normal compare with damaged cashew apples, 77.7% and 51.0% respectively. The best seed quality and viability was seed from normal cashew apples

Abstract

Gambier (Uncaria gambir Roxb.) is a useful plant, especially for for the pharmaceutical industry. Productivity of gambier is still low because one of them caused by low soil fertility in cropping areas gambier. This study aimed to determine the relationship of soil nutrient content, nutrient content of plant and crop production of gambier at the one of production centers in West Sumatra for the basis of determined fertilizer needs of gambier. The experiment was conducted with a random sampling method on the plot owned by farmers in the Kampung Koto Marapat, West Sumatra.The results showed that each ton of dry leaves of gambier will take the nutrients of 19.8 kg N, 1.3 kg P and 13.6 kg K. High yield crops need nutrients at 452 kg N / ha, 30 kg P / ha and 296 kg K / ha with population 2500 plants / ha. The high production of gambier is not indicated significantly by high levels of NPK nutrients in leaf and high soil nutrient levels. Low pH was one factor limiting the production of gambier.

Abstract

Cashew growing in Indonesia is mainly addressed to economic reasons rather than soil and waterconservations of some degraded soils. Main producing areas of the crop are Southeast Sulawesi, South Sulawesi, East Java, Cen tral of Java, East Nusa Tenggara and West Nusa Tenggara provinces covering about 500.000 ha or about 90% of Indonesian cashew. In general, mean yields of the crop is much lower than those of other producing countries like India and Vietnam. Many factors believed affect low in yields of the crop. Increasing in composition of damaged cashew trees to those of the health ones may bring about steadily declining production of Indonesian cashew. In turn, meanyields of the crop achieved are low. Rehabilitation programs of cashew orchard at field levels are therefore needed, mainly to the main growing areas of cashew trees. Field actions that might be implemented for the purposes are pruning, thinning and replanting with high yielding varieties or clones of cashew. To accelerate of recovering of cashew trees, other orchard managements like fertilizing and controlling of some im portant pest and diseases of the crop should be accomplished in better ways.
